Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Any other information on results incl. tables

The minimum and maximum values for molecular weight and logKow are listed below. Currently there is no universally accepted definition of model domain.  However, users may wish to consider the possibility that bioconcentration factor estimates are less accurate for compounds outside the MW and logKow ranges of the training set compounds, and/or that have more instances of a given correction factor than the maximum for all training set compounds.  It is also possible that a compound may have a functional group(s) or other structural features not represented in the training set, and for which no fragment coefficient was developed; and that a compound has none of the fragments in the model’s fragment library.  In the latter case, predictions are based on molecular weight alone. Training Set (527 Compounds):

Molecular Weight:  Minimum MW:  68.08  (Furan)  Maximum MW:  991.80   Ionic  Maximum MW:  959.17   Non-Ionic  Average MW:  244.00

Log Kow:  Minimum LogKow:  -6.50   Ionic  Minimum LogKow:  -1.37   Non-Ionic  Maximum LogKow:  11.26

Applicant's summary and conclusion

Conclusions:
Toxicity of the target chemical (3.162 L/kg wet) is predicted by QSAR "BCF (EPISUITE)".
